PARTITION.

SPECIFICATION forming part of Letters Patent No. 504,858, dated September 12, 1893.

Application iilerl August 10, 1892. Selial No. 442,735. (No model.) l l To all whom it may concern;

Be it known that I, THOMAS BAILEY, acitif zen of the United States, and a resident of New York city, in the county and State of New York, have inventedcertain new` and Figure 1, is a'front" elevation of a portionA of the skeleton of a partition as I now construct it preparatory to applying the plaster,

with a part broken out. Fig. 2, is an end elea vation of a portion of a like skeleton, with a flange at one end to abut on and fasten to a wall or transverse partition. Fig. 3, is partly an end elevation and partly a sectionalelevation of alike skeleton with a flange at the top of one of the upright strips to fasten to i the under side of an upper floor beam.` Fig. 4, is a detail in vertical section showing some of the parts in modified form. Fig. 5, is a transverse sectional elevation of a ceiling in accordance with my invention. Fig. 6, is a side elevation of a partition partly covered with plaster and a section of a portion of a ceiling ot' my invention, on a reduced scale.

The reversely bent and alternately dovetail ribbed and grooved metallic sheets a, to be covered on one or both sides with plaster t, as for a partition or ceiling, are the same as in my former patent referred to, and the posts or rods c, extending lengthwise ofthe plates through the 4perforated cross-webs formed in producing the dovetail ribs or grooves, and employed to stien them may also be used with my present improvements if desired, and I so represent them in the drawings, but they may be omitted.

I now propose to employ at bars as d,

transversely to the said dovetail ribs and grooves or lengthwise of the plates and applied to the outside for stiening them. I pre1 fer to connect said bars by'means of the ilaring yoke cleats e, attached to `or formed ron said bars the distance apart corresponding with the pitch of the grooves, and adapted to connect with the plates by sliding intothe grooves lengthwise from the edges of the plates; these flaring cleats being of the same width where they join the bars as the narrow `openings of the grooves, justifythe ribs and grooves which owing tothe thin and unstable character of the plates do not retain such uniform relation of the parts when placed in position as is desirable especially l when the rods c, only are used for stiffening i and adjusting the plates; the cleats also draw the plates and bars closely and rmly together through the eect of the flaring shape of the cleats and the undercut form of the grooves. To facilitate the entering of the ends of the cleats in the ends of the grooves, the cleats are made tapering from the middle to the Vends as shown in Fig. l whereby the ends of the cleats will enter the grooves when closed more than their due dimensions and the wider middle portions of the cleats spread the grooves to the proper extent. i

By another` plan expansible cleats as e', `somewhat narrower than the grooves so as to enter freely maybe expanded by taper nuts f, and screw bolts g, inserted` through the plates d, and the cleats, the said bolts and nuts also .being the means of securing the cleats to the bars, or the cleats may be otherwise fastened. The cleats and bars may be integral castings as in Figs. 3, ft, and 5. These bars d, may be used at the edges of the plates only, where besides stiffening the plates and justifying the ribs and grooves they serve to couple two plates together, the plates being placed edge to edge and the bars and cleats `applied half to each plate as in the middle of Fig. l, other bars may be usedy at intermediate positions along the sheets as in the places of theV rods c. The coupling or splicing and intermediate bars d, will have a iiange as 'L' at each end to fasten on the floor at the lower end and on the under side of a beam or ceiling at the upper end, and where the end of a partition joinsa transverse partition, or a side IOC Wall as la at the' right hand"of'-Fig.-5,the bar d, will have avfiange j along one'edge to fasten to said transverse partition or wall.

I propose in some cases to emply other stiffening bars d', on the other sides of the sheets together with bars d, either rivetingy them on as at Z, Fig. 3, or bolting or riveting them through the plates and bars d, as by the bolts m, fn. These bars d will be more particularly useful in the case of ceilings as in Fig. 4, and the bolts fn, will have an eye o, a suitable distance. above the bar d, for suspending the fire proof material from the wood beams p, by spiking the eyes tothe beams. The length of the eye portions of the bolts above the bars d,fwill be such as to aord ample air space between thennetallicv portion lot `the ceiling" and the wood for protection against lire. Bolts g may also have eyes for suspending the yceil ing. in like manner. When the rods c are used the plates a, are perforatedl at suitable distances apart before bendingthem to cause the holes te come in line suitably for admit# tingthe rods. The rods have ange collars as s, at the ends onthefioor or ceiling. i

t represents the plaster appliedto the cei-l-v ing in Fig.' l, and to the partition in Fig. 5.
